OK, I'm buffalo'd here. Wanting to run a Level-1 Diagnostic on an auto trans, as per procedures in Bentley. But Bentley's verbage leaves me with quite a few unanswered questions. Can anyone who's done this offer a real-world explanation of the whole vac-pressure testing operation? Alternate methods that have worked for you? How should these hoses be connected to the test outlets? Are there special fittings I oughta be looking for, to avoid damaging the connections in the tranny case? Should I be concerned about the pressure ratings of the hoses I'm using? And what sort of guages should I be looking for? Also, there's talk of taking pressure readings & making adjustments with the main vacuum hose disconnected... and then, later, taking the readings again under driving conditions, with the hose hooked up. Am I correct in thinking that readings with the hose off are meant to establish a baseline, because the setup mimics a "nil" signal from the engine? And if all this pressure testing reveals that something in the valve body is shot, would I be better off trying to hunt down & replace the actual broken bit? Or just getting a whole new unit? Do new/reconditioned AT valve bodies even exist? The book makes it look like the valve body is 100% serviceable... by someone with way more experience and a better-outfitted garage than I have. Please advise. Thanks. --timmy '72 square (4 on the floor, no worries) '69 square (wife HAD to have the *#$@%* automatic!)
